The burners are produced with connections suitable for power supply 380-400 V three-phase.
The burners with electric motors of an output lower or equal to 3 kW can be adapted to 220-230 V (please follow the
instructions on the backside); motors with higher output can only work 380-400 V three-phase.
In case of request of burners different from the above mentioned standard, it is recommended to make specific mention
in the order.
Instructions: how to adapt electric motors of an output lower or equal to 3 kW to 220-230 V power supply
It is possible to change the voltage of the burner by operating as follows:
1. change the connection inside the electric box of the motor, from star to delta (see picture);
2. change the setting of the thermal relay, referring to the absorption values indicated in the motor nameplate. If
necessary, replace the thermal relay with another one of suitable scale.
This operation is not possible on motors above 3 kW.
For more information, please contact the Ecoflam staff.
YEARLY CHECKS
The burner's periodical check (firing head, electrodes etc.) must be carried out by authorised personnel one or two
times per year, depending on the utilisation. Before going on with the maintenance controls of the burner, it should be
advisable to check its general conditions, according to the following steps:
Unplug the burner; close the fuel cock; shut down the gas supply; remove burner's cover and clean the fan and air
intake; clean the firing head and check the electrode's position; reassemble all the parts; check the connection's sealing;
check the chimney; start the burner and check the combustion flue (CO2 = 9.5 ÷ 9.8; O = lower than 75 ppm).
BEFORE EVERY INTERVENTION CHECK:
The electric system is duly powered and the burner is plugged in.
The gas pressure must be the suitable one and the gas cock open.
The control devices must be properly connected.
When all the above conditions are met, start the burner by pressing the lockout enable pushbutton.
Check the burner's cycle.
THE BURNER DOES NOT START:
Check the ON/OFF switch, the thermostats, the motor and the gas pressure.
The master switch is in position "0". Fuses are blown out.
The control box is faulty.
THE BURNER RUNS THE PREPURGING AND SWITCHES TO LOCKOUT AT THE END OF CYCLE:
Check the fan and the air pressure.
Check the air pressure switch.
Control box faulty. Ignition transformer faulty.
Check the ignition cable. Electrodes are dirty or in wrong position.
Nozzles are clogged or worn. Filters are clogged. Light-oil pressure is too low.
Combustion air's flow rate too high related to nozzle output.
THE BURNER RUNS THE PREPURGING BUT DOES NOT IGNITE:
Check the position of the electrodes; check the ignition cable;
Check the ignition transformer;
